Struct NegativeResult 

pub struct NegativeResult {
    pub id: String,
    pub kind: NegativeResultKind,
    pub target_findings: Vec<String>,
    pub deposited_by: String,
    pub conditions: Conditions,
    pub provenance: Provenance,
    pub created: String,
    pub notes: String,
    pub review_state: Option<ReviewState>,
    pub retracted: bool,
    pub access_tier: AccessTier,
}

Fields

id: String

vnr_<16hex>, content-addressed; see NegativeResult::content_address.

kind: NegativeResultKind

The kind-specific payload.

target_findings: Vec<String>

vf_* findings whose positive claim this null bears against. May be empty — exploratory dead ends don’t always have a pre-existing claim to negate.

deposited_by: String

Stable actor id of the depositing lab / curator / agent.

conditions: Conditions

Conditions under which the null was observed. Reuses the Conditions shape so model relevance, scope, and translation boundaries flow through to downstream confidence math.

provenance: Provenance

Provenance of the trial readout / paper / preprint / lab notebook.

created: String

RFC 3339 creation timestamp.

notes: String

Free-text reviewer note. Often the most important field — the “why this null matters” or “why we ran this in the first place” context that licenses use as a dead-end signal.

review_state: Option<ReviewState>

Optional review verdict. Mirrors the Flags.review_state pattern on FindingBundle so reviewed/contested/needs-revision nulls are first-class state.

retracted: bool

True once a negative_result.retracted event has been applied.

access_tier: AccessTier

v0.51: Read-side access tier. See FindingBundle.access_tier for the doctrine. Defaults to Public and skips serialization when public so pre-v0.51 frontiers round-trip byte-identically.

Implementations

impl NegativeResult

pub fn content_address( kind: &NegativeResultKind, deposited_by: &str, created: &str, conditions: &Conditions, ) -> String

Compute the content-addressed ID per v0.49 spec: SHA-256(kind.canonical() | deposited_by | created | normalize(conditions.text)). Returns first 16 hex chars prefixed with “vnr_”.

pub fn new( kind: NegativeResultKind, target_findings: Vec<String>, deposited_by: impl Into<String>, conditions: Conditions, provenance: Provenance, notes: impl Into<String>, ) -> Self

Construct a new NegativeResult with a freshly-derived id and created timestamp set to now.

pub fn is_informative_trial_null(&self) -> Option<bool>

True when the null is informative under the registered-trial criterion: adequate power AND CI excludes the pre-registered MCID. Returns None for exploratory nulls or trials missing the required fields. Used by downstream confidence math to distinguish “absence of effect” from “absence of evidence.”

Trait Implementations

impl Clone for NegativeResult

fn clone(&self) -> NegativeResult

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for NegativeResult

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for NegativeResult

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for NegativeResult

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
